Done. There doesn't appear to be any way that Mir itself can screw up that call. It's possible qtmir might be messing up with an incorrect 'this' pointer to the Mir DisplayBuffer. But I think much more likely that it's a nouveau driver bug. If it wasn't then we'd be seeing similar crashes with intel and radeon, but we don't. ** Changed in: libdrm (Ubuntu) Importance: Undecided => High -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to libdrm in Ubuntu. https://bugs.launchpad.net/bugs/1553328 Title: unity8 crashed with SIGSEGV on nouveau, in eglMakeCurrent() ... nv50_flush() ... pushbuf_kref() To manage notifications about this bug go to: https://bugs.launchpad.net/mir/+bug/1553328/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

We should sanity-check the correctness of the eglMakeCurrent call in Mir src/server/graphics/nested/display_buffer.cpp:62 But other than that, it seems to be purely a nouveau bug. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to libdrm in Ubuntu. https://bugs.launchpad.net/bugs/1553328 Title: unity8 crashed with SIGSEGV on nouveau, in eglMakeCurrent() ... nv50_flush() ... pushbuf_kref() To manage notifications about this bug go to: https://bugs.launchpad.net/mir/+bug/1553328/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
